Ben Leber's role at outside linebacker has become more important since E.J. Henderson's injury, and Leber said he believes the team has regained its early-season form in beating the Giants after losing to the Cardinals, Panthers and Bears. Leber said the team is ready for a top performance Sunday against the Cowboys.

The Vikings were 10-1 -- the only loss being to the Steelers -- before they went into the slump and lost three out of the next four games.

You want my opinion? The Vikings will have to play like they did when they were 10-1 if they are to beat the Cowboys and advance to the NFC title game. Anything less will result in the season coming to a close. The Cowboys completely dominated a pretty good Eagles team in two consecutive games.

"Those are the lumps you end up taking over the course of the year. It's a long season," said Leber, about the Vikings' roughest stretch. "We did a great job bouncing back and collecting ourselves.

"We played our style of football [against the Giants], and that's the sign of a good team. We executed very well, and we set out and did the things we wanted to do."

The final 12-4 record gave the Vikings a bye week. "Certainly, the week off helped," Leber said. "It let us get our bodies healthy, and get mentally fresh."

Leber was asked if replacing Henderson, maybe the best middle linebacker in the league, when the Vikings are in the nickel defense, has put more pressure on him than when he plays outside linebacker.

"I don't feel like it's too much," said Leber. "I got my feet wet last year with him going down during the season. I feel comfortable out there right now."

Leber said the Vikings had a great week of practice preparing for the Cowboys.

"The game plan is great and the guys are excited for the game," Leber said.

How big is this game?

"It's a big game. I can't put a number on it or say how big it is, but it's a big game," he said. "It's the playoffs, and everybody understands if you lose, you are out. Win, you have another chance and the opportunity to go to the Super Bowl."

Top defense Vikings Pro Bowl tackle Steve Hutchinson is impressed with the Cowboys defense.

"They are a top-notch defense. I don't think anybody will argue that," Hutchinson said. "Their pass rush is second to none. They are a complete defense. The last four games, they have been able to really tee off. The Cowboys offense has been doing a good job putting up points. So, the defense hasn't really had to contend with the run. They have been able to showcase their pass rush the last couple of games."

Fellow tackle Bryant McKinnie, who had some problems this year, being removed from the Panthers game, was asked how he was going to handle DeMarcus Ware, the great Cowboys linebacker.

"I'll be blocking him from time to time," McKinnie said. "I have a little game plan I'm going to use against him, but I'm not going to discuss it."

How good is he? "He's a pretty good pass rusher," said McKinnie. "He's one of the top pass rushers in the NFL. He's a good player, but he's going to be facing a pretty good offensive line."

Crowd will help Brett Favre said he expects the crowd to be a 12th man on Sunday. "As a member of the Packers, I learned that without a doubt the Metrodome was the toughest place to play from a noise standpoint," he said. "[Dallas quarterback] Tony Romo will have a new experience."

Vikings center John Sullivan said the last thing he ever expected in his career was being the center for Favre.

Vikings owner Zygi Wilf, who expects the club to break even financially this year, has been here since Thursday watching practice every day and conferring with the coaches. He says he isn't nervous about the outcome of today's game, but is confident the team will play its best of the year.

Dallas coach Wade Phillips hopes that ex-Gopher running back Marion Barber III is ready to play after being bothered by a sore knee, and can offer a different look from Felix Jones. "It is hard to focus on one running back and another coming in. Me, I don't play defense, but I figure it's hard," he said. "They have to adjust, to it so it helps a lot."
